Whitney Mercilus, DE, Illinois

Whitney Mercilus out of Illinois is one of the top defensive end prospects in the 2012 NFL Draft. So far in 2011, he's piling up awards recognition nearly as fast as sacks and tackles for loss. He currently leads the nation in sacks (13.5), sacks per game (1.23) and forced fumbles (8). Mercilus is also a Bronko Nagurski Trophy finalist, an award given to the nation's best defensive player.

What Mercilus lacks in athleticism he makes up for in consistent effort. He really often sells out on pass-rushing and abandons his gap assignment to rush the passer. He can play both defensive end positions and does well to change up his style, whether it be a bull rush or going inside/outside.

Should only be considered a 4-3 defensive end. Although he has the size to play 3-4 OLB, he doesn't have the fluid hips or the footwork necessary yet to play in coverage. At the next level, he'll need to learn how to be more explosive off the line and stay in his lane since teams often run right at where he is supposed to be.

His pad level after contact gets high, which is a big problem for scouts. For a guy with his size, he doesn't have a strong base and will likely need to beef up his lower body to hold his ground.
